The B&W TS10033C Tow & Stow Chrome Dual-Ball Trailer Hitch Mount features two separate ball sizes in 2" & 2-5/16", eliminating the need for multiple ball mounts. It adjusts to multiple heights and can be stowed underneath the vehicle when not in use. The Tow & Stow Chrome Dual-Ball Hitch mount improves your vehicle's appearance and keeps the hitch from obstructing surrounding areas. To use, rotate the ball to the size needed for towing, then adjust the height in one-inch increments.
